My car developed a problem where it would lose power intermittently while running. The power would come and go before the car eventually dies. Sometimes it starts momentarily and sometimes it takes much, much longer. I’ve replaced the fuel pump and the camshaft sensor but the problem persists. My last options may be the crank sensor or the ignition module. Any thoughts ? ---

Crank sensor - change it, and go from there. ---

Does this car have a fuel pressure regulator on the intake. Also, a friend had a bad coil and maf that was causing problems like this. If it’s a bad injector, be careful, the injectors listed on many web sites are wrong. Yours has 4 spray holes and differnt fuel flow characteristics.
